Hint 4:
If the injector activationtime deviates from the
standardvalueeven thoughtheresultsofthe
checking of the injector's harness and of the in-
jectoritselfarenormal,thecausemaybe
presumed to be one of the following:
(1) Incomplete combustion within the cylinder.
(Malfunctionof the spark plugs, the ignition
coil, the compression pressure, etc )
(2) Improper adhesion of EGR valve sheet:
(3) Increased engine resistance:

NOTE
Indicatesthe injector-activation time when the power source voltage is 11V ad the cranking speed is 250 rpmless_
At a coolant temperature of 0PC (32*F), there is synchronous injection for allfourcylinders.
For a new vehicle [driven approximately 500 km (300 miles) or Iess] the injector-activation may be about ten percent
longer then indicated above.

Wave Pattern Inspection Using an Analyzer
Measurement method
(1) Disconnect the injector connector, and connect the spe-
cialtool(testharness:MB991348)inbetween.(The
power sideand the ECU side terminals should both be
connected )
(2) Connect the analyzer special patterns pickup to the ECU
test harness clip.
